JOHN MARSTON, OF SARATOGA SPRINGS, NEW; YORK.

Letters Patent ,N 96,130, dated October 26, 1869.

IMPROVED RAILWAY-CAR COUPLING.

The Schedule referred to in these Letters Patent and making part of the same.

the same, reference being bad to the accompanying drawings, forming part of this specification.

This invention relates to improvements in shackles for connecting cars together in trains, and consists of an improved arrangement of double-jointed bar specially adapted for connecting cars of different heights.

Figure 1 represents a longitudinal sectional elevation of my improved shackle, showing also the application to cars of different heights, and Figure 2 represents a plan View of the same.

Similar letters of reference indicate corresponding parts.

The stock a, consisting of a strong bar of metal considerably enlarged at the ends, has a slot, B, at one end, for the reception of a tongue, (l, of a link, I), and is fitted, at the other end, to the slotted end of another link, E, in which it is secured by ajoint-bolt, F. l

The tongue 0 of the link D is pivoted to the stock on thebolt G, and is provided with a curved slot, H,

behind the said bolt, through which a bolt, 1, passes.

The end of the stock is bevelled from the centre each-way, as indicated by the lines a, and thelink D has shoulders, b, to bear against the end of the stock in backing the train.

The tongue 0 terminates in a tapered projection, 0, against which two flat springs, K, secured to the stock, near the opposite end, bear, to maintain the link-normally in line with the stock.

These joints of the links with the stock are arranged for oscillation vertically when the shackle is in position, the said links being coupled to the buffers L, by the coupling-bolts M, in the usual way.

It will be seen that by reason of the arrangement of the additional bolt I, and the curved slot in the connection of the link 0 with the stock, the force of the draught is divided between two points, both on the stock and on' the link; also, that in backing the train the. strain is, by reason of the said arrangement, and the bevelled ends of thestock, and the shoulders b of the shackle, divided between three resisting points on each, thereby greatly increasing the efiiciency of y the apparatus.

This shackle is more especially intended for use in connecting cars to the tenders, but is applicable in making all connections.

When the linkD is disconnected, it swings down on the joint-bolt F, as represented in dotted lines at O.

The links have also shoulders, 2, bearing against the buffers.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combination of the stock A,links D E, and springs K, when the link D is jointed to the stock, and all arranged substantially as specified.

The above specification of my invention signed by me, this 7th day of September, 1869. l
